Where can find help on USB Bulk Transfer between PC and Nucleo-H743ZI.

While working on Nucleo-H743ZI , I have downloaded the related examples and using USB CDC class example I have created a test App tool on Windows PC which connects to the Nucleo where STM code using HAL USB CDC sends and receives data with the PC.

Now I want to switch from CDC to Bulk transfer but so far couldn't get any source code HAL example of Bulk . Can someone point me to any available resources as I am very new to USB .
